SIDE BEARING FOR RAILWAY-CARS.

Specification of Letters Patent.

Patented Apr. 17, 1917.

Application filed March 1, 1916. Serial No. 81,325.

To all whom it may concern:

Be it known that I, JOHN F. OOONNOR, a citizen of the United States,residing at Chicago, in the county of Cook and State of Illinois, haveinvented a certain new and useful Improvement in Side Bearings forRailway-Oars, of which the following is a full, clear, concise, andexact description, reference being had to the accompanying drawings,forming a part of this specification.

My invention relates to improvements in side bearings for railway cars.7 1

The object of my invention is to provide a simple and efficient sidebearing.

In the drawings forming a part of this specification, Figure 1illustrates an end view of my improved side bearing in position betweenthe bolsters,only part of the bolsters being shown in the drawing. Fig.2 is an enlarged longitudinal section taken on line 22 of Fig. 1. Fig. 3is a cross section on line 33 of Fig. 2, in which the bearing is in itsnormal position. Fig. 4 is an end view of the bearing in a laterallydeflected position.

In the drawings, the numeral 5 indicates the body-bolster of a' railroadcar, and 6 the truck-bolster,-only a portion of the bolsters beingshown. A bearing plate 7 is provided upon one of the bolsters,preferably the body-bolster, which is adapted to be engaged by therollers of the side bearing 8. The

side bearing is mounted upon the bolster '6, and comprises a cradle .9within the hollow recess 10 of which are mounted the rollers 1111, thesaid rollers being arranged transversely of the cradle and each havingan axle 12 extending through the perforation 13 in the roller andreceived at its ends in the hollow protuberances 14 upon the cradlewithin which the axle is secured by -means of cotter pins 15. At itsbottom the cradle is provided with a longitudinally extended crown 16which near the ends of the cradle forms a convexv bearing resting uponthe adjacent bolster. to the bolster by suitable means such as therivets 17-17 passing through the flanges 18-18 with which the cradle isprovided at its ends.

The cradle is secured The rivets 17-17 are applied in the usual mannerand are adapted to hold the cradle first in horizontal position. In theevent the cradle is tilted to either side, the rivets will be bent andslightly stretched, but on account of their rigidity will hold thecradle in any tilted position and in tight contact with the, adjacentsurface of the bolster.

I claim v 1. In a side bearing for railway cars, the combination with abolster, a cradle, and a roller carried by said cradle, of rivets, thecradle being provided on its lower face with a crown, and the rivetsbeing adapted to secure the cradle in any fixed position to' 3. In aside bearing for' railway cars,

rollers, a cradle therefor, a bolster and means securing the cradle tothe bolster, the cradle being provided with a crown adjacent thebolster, the means securing the cradle to the bolster being adapted tohold anyportion of the crown in a fixed position upon the bolster.

4. A side bearing for railway carscomprising a cradle provided withcrowned faces on the bottom thereof, a roller rotatably mounted withinsaid cradle, the axis of the roller being at right angles to the axis ofthe crowned faces, the cradle being provided with perforations at thebottom thereof and extending through said crowned faces, saidperforations being adaptedto receive securing means for attaching thecradle to a bolster, whereby the cradle may rock on said crowned facesdirectly on the I bolster.

In witness that I claim the foregoingI have hereunto subscribed my namethis 16th day of February 1916.

JOHN F. OCONNOR.
